IMPROVEMENT IN HUBS FOR CARRIAGE-WHEELS.v

Specification forming part of Letters Patent No. 132,241, dated October15, 1872.

To all whom it may concern:

Be it known that we, BoBT. BROWN and W. ALDRIGH, both of Dayton, in thecounty of Montgomery and State of Ollio, have invented a new andvaluable Improvement in Hubs 5 and We do hereby declare that thefollowing is a full, clear, and exact description oi' the constructionand operation of the same, reference being had to the annexed drawingmaking a part of this specification, and to the letters and figures ofreference marked thereon.

Figure l of the drawing is a representation of a vertical section of ourinvention. Fig. 2 is a vertical longitudinal section of our invention.

bands rectangular mortises are cnt or formed. The mortises of both bandsare of equal size, i and when brought together correspond. The hub B isof wood, and has an annular groove, C, out around its middle portionwide enough to admit the ends of the spokes, which are passed throughthe band mortises, and of such depth as to leave wood, c, around theaxleboX to support the hub and form a bearing for the ends of thespokes. The middle portion of the hub is convex or bulging. The bandsare put on the Wooden hub, the one iitting inside the other; themortises in the bands and the groove in the hub being nearly even witheach other. The spokes are then driven in, the tapered end or each llinga sector-space in the groove, and all the spokes together completelylling the groove. By reason of the tapering form of the bands, when theyare put.

on the convex hub and the spokes driven home said hub is pressed inwardand thereby greatly strengthened. It will be observed that these bandsrequire no other fastening than the spokes. v

What we claim as our invention, and desire to secure by Letters Patent,is-

1. The male and female hub-bands A A', correspondingly beveled andmortised, substantially as and for the purpose speeiiied.

2. The combination of the male and female mortised bands A A and thegrooved hub B, substantially as described,

In testimony that we claim the above we have hereunto subscribed ournames in the presence of two witnesses.

ROBERT BROWN.
